DESCRIPTION
This Cmdlet unregisters an already registered symbol handle from the target system.
The Cmdlet supports raw \[uint\] handles or AdsHandleInfo objects.
EXAMPLES

PS> $handleInfo = $session | get-AdsHandle -Path 'TwinCAT_SystemInfoVarList._AppInfo.ProjectName'
PS> $handleInfo = register-AdsHandle -Path 'TwinCAT_SystemInfoVarList._AppInfo.ProjectName' -Session $s
PS> $handleInfo
